CARRY-IRON.

Specification of Letters Patent.

Patented Feb. 26, 1918.

Application fi1ed April2,'1917. Serial No. 159,099.

To all "whom it may concern:

Be it known that we, Jon)? H. TINKER and DAVID T. HARRIS, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carry-Irons, of which the following is a specification.

Our invention relates to railway cars, and

particularly to a device for supporting the drawbars of such cars.

It. is frequently necessary to remove the drawbars or draft rigging of railway freight cars. and to this end means are commonly provided for supporting the drawbar near the end of the car in such manner as to readily permit the coupler to be dropped. To this end many forms of carry irons have been provided. The present improvement, however, relates to a device in which the drawbar is supported upon a broad plate, and novel means is provided normally for holding the plate in its operative position.

An object of the present construction is to provide a carry iron which may be interlocked with the buffer casting in a suitable manner and which provides such extensive bearing surfaces as to make the wear negligible.

The invention will be more readily understood by reference to the accompanying drawings in which,

Figure l is a perspective view of a buffer casting and a carry iron constructed in accordance with our invention, a portion of the casting being broken away to show the method of engagement between the supporting plate and the castin Fig. 2 i a perspective view of the supporting plate or bar.

Fig. 3 is an enlarged, sectional view showing the locking dog in position, and,

Fig. 4 is a view of a modified form of locking means.

In the drawings it will be seen the bufier block, to which my improvement relates, includes a back wall or fastening plate 10, having bolt holes 11, depending side walls 12, and a top wall 13. The marginal front edges of the top and side walls are provided with lateral flanges 1415, the flange 14: which engages the coupler horn being braced by suitable webs l6. Near the lower edges the depending side walls 12 are provided with horizontally elongated apertures or slots 17 of substantial length and of a height slightly greater than the thickness of the plate or bar 18 which serves to support the drawbar. he plate 18 is provided with transverse grooves 19 near its ends, the grooves being so spaced as to enable the insert-ion of the plate within the slots 17, and theinterlocking of the plate with the'fianged lower edge 20 of the opening.

Preferably means will be provided for locking the bar 18 in its position. Such means may include a gravity actuated pawl or dog 21 pivoted on a riveted shaft 22. The lower face of the pawl may, if desired, be slightly eccentric in order to insure a secure holding engagement even after wear has taken place between the parts. We may or may not provide one of these locking pawls at each end of the bar 18.

In the construction shown in Fig. 4 a slightly modified form of locking means is provided. In that construction the bar 23 is of the same form as that heretofore de' scribed, but a spring 24 is bent into arcuate form and is secured by means of a rivet 25' to the plate. The distance between the end 26 of the spring and the top of the plate 23 is greater than the height of the opening 27 in the casing. Thus it is impossible to remove the plate 23 from the position shown in Fig. 4 without first lifting the same, then bending the spring 24 toward a horizontal position; the plate may then be readily removed lengthwise through the opening.

By the provision of the means described in connection with a bar having this large bearing area, it will be found that wear will be negligible and that all danger of dropping of the coupler due to disengagement of any of the holding parts will be eliminated.

We claim:

1. A buffer block and carry iron, comprising in combination, a casting having de pending side walls each provided with an aperture near its lower edge, and a relatively wide plate having grooves near its ends, said plate by means of said grooves and apertures being adapted to removably interlock with said casting, retained by gravity, and removable laterally through said apertures.

2. A drawbar carry iron, comprising in combination, a member having a back wall, top and side walls, a plate having notched ends adapted to engage said side walls near the lower edge thereof, and movable means normally for locking said plate in its operative position againstan upward movement.

3. A drawbar carry iron, comprising in combination, a member hzwing a back Wall, top and side Walls, a plate having notched ends adapted to engage said side Walls near the lower edge thereof, and a pawl for pre venting the disengagement of one of the notched ends of said plate from the adjacent side Wall.

4. A draivbar carry iron, comprising in combination, a pair o? vertical Walls spaced apart to accommodate a coupler shank therebetween, and each provided with an elongated horizontal slot near the lower edge thereof, a relatively broad plate having grooves in its side adapted to engage the Walls of said slots, and locking means for retaining said grooves in locking engagement With said Walls normally to prevent an endwise withdrawal of said plate.

5. A drawbar carry iron, comprising in combination, a member having side Walls with apertures therein, and a plate having notches adapted to engage said side Walls adjacent said apertures and removable laterally through the apertures.

Signed at Chicago, Illinois, this 31st day of March, A. D. 1917.
